There isn't much in Kamchatka, a remote peninsula in northeastern Russia just across the Bering Sea from Alaska, besides an impressive population of brown bears and the most explosive volcano in the world.
Ny forskning visar nu att radioaktiva ämnen var med och formade de innersta planeterna i solsystemet. Det bidrog till att Merkurius, Venus, jorden och Mars blev torra stenplaneter till skillnad från de väldiga is-världarna som Uranus och Neptunus. Spela videon för att se hur de radioaktiva ämnena kom dit.

Written language, photography, calenders and time, etc. What about enhancement of working memory and improvement of executive functioning? In my opinion, cell phones and televisions dampen executive functioning. Written language replaced classical Mnemonics, which further reduced the usage of our mind. What can be don
Hi everyone, I have been reading a lot about free will and the most recent neuroscience experiments in that field. However, one way question troubles me to which I have never been able to find any study. We know that neurons fire when depolarization occurs, phenomenon that we call action potential. Depolarization occurs following a stimulus. Stimuli mostly come from chemical synapses, sensory neu

As is now traditional, every year around this time we update the model-observation comparison page with an additional annual observational point, and upgrade any observational products to their latest versions. A couple of notable issues this year. HadCRUT has now been updated to version 5 which includes polar infilling, making the Cowtan and Way dataset (which was designed to address that issue
Dramatic changes were seen in the delivery of radiotherapy treatments for cancer during the first wave of the coronavirus pandemic in England. Much shorter radiotherapy courses were delivered, treatments were delayed where it was safe to do so and some increases were seen in order to compensate for reduced surgical capacity. Experts believe the changes reflect an impressive adaption of services by
BioNyt Videnskabens Verden (www.bionyt.dk) er Danmarks ældste populærvidenskabelige tidsskrift for naturvidenskab. Det er det eneste blad af sin art i Danmark, som er helliget international forskning inden for livsvidenskaberne.
Bladet bringer aktuelle, spændende forskningsnyheder inden for biologi, medicin og andre naturvidenskabelige områder som f.eks. klimaændringer, nanoteknologi, partikelfysik, astronomi, seksualitet, biologiske våben, ecstasy, evolutionsbiologi, kloning, fedme, søvnforskning, muligheden for liv på mars, influenzaepidemier, livets opståen osv.
Artiklerne roses for at gøre vanskeligt stof forståeligt, uden at den videnskabelige holdbarhed tabes.
